IMPROVEMENT IN WHEELS FOR HARVESTERS.

Specification forming part of Letters Patent No- 60,5 16, dated March 9, 1875 application filed January 16, 1675.

To all whom it may concern:

Be it known that I, GUILFoRn D. RowELL,

,of Appleton, in the county of Outagamie, in

the State of Wisconsin, have invented certain Improvements in Hubs and Axle-Trees, of which the following is a specification:

My invention has for its object the improvement of seeders and other agricultural implements, and is accomplished by the application of a thimble-skein with a hub slipping on over same, and secured in its place by a stem passing through the skein with a cog-wheel on end of it, and a square collar fitting onto the other end of the stem, which end is made square for the fitting on of the collar, and a square recess in the end of the hub, into which the collar fits, and a nut screwed onto the end of the stem outside of the collar.

Figure l is a sectional View of my invention. Fig. 2 is a view of the cog-wheel and Fig. 3, a sectional View of the end of the stem and hub for the ground-Wheel in line 90 av, Fig. l.

A is the thimble-skein; B, the hub for the ground-wheel, fitting on over same; 0, the collar on the end of the stem; D, the stem running through the thimble-skein. This stem is made as follows: A rod of wrought-iron the proper length is set in the sand for a core, and then the cast-iron run in around it, which, sticking to it, forms the stem, and also chills the same. G, the cog-wheel for running the seed-works of the seeder; H, a head on the stem which holds the cog-wheel on; I, lugs in the head, which, fitting into recesses in the cog-wheel, revolve it, this stein being revolved by the hub fitting onto collar 0. This thimble-skein is secured to the seeder in any way thought best.

I claim as my invention l. Thimbleskein A, hub B, collar 0, stein D, and nut E, all in combination, substantially as described.

2. Thimble-skein A, stem D, with its head H, lugs I, and cog-wheel G, all combined sub stantially as specified.
